Description
Technical field
The present invention relates to technical field of polymer materials, be specifically related to a kind of solid lubrication anionic reactive nylon and preparation method thereof.
Background technology
Anionic reactive nylon (general name of monomer cast nylon, reaction injection nylon and reactive extrursion nylon) owing to adopting the method for anionoid polymerization, speed of response quickly, so be called for short rapid polymerization nylon.This kind of nylon is a kind of engineering plastics of excellent property, compared with common nylon 6, and molecular weight is higher, degree of crystallinity is high, mechanical property, self-lubricating property are good and the size of moulded products is unrestricted etc. feature that it has.Therefore, anionic reactive nylon in mine, metallurgy, machinery, light industry, chemical industry, weaving, papermaking, the field such as video have and generally apply.
At present, anionic reactive nylon is widely used in engineering machinery as wearing piece, but the development of technology thereupon, and simple anionic reactive nylon can not meet the demands.But, many performances of anionic reactive nylon, such as mechanical property, processing characteristics, frictional behaviour and fusing point, degree of crystallinity etc., often can not improve simultaneously, even usually produce shifting effect, be thus unfavorable for the raising of anionic reactive nylon over-all properties.According to adding multiple properties-correcting agent or producing anionic reactive nylon by multiple modification procedure, then need to improve material cost and equipment cost, increase the complicacy of production technique.Therefore, the anionic reactive nylon that the performance balance that can produce with the step of simple raw material, condition and simplification of exploitation is good has obvious industrial production meaning.
Summary of the invention
The object of the present invention is to provide the anionic reactive nylon that a kind of performance balance is good, it is prepared by simple step with simple material formula, and by adding suitable solid lubricant, it is made not only to have superior frictional behaviour, can also keep excellent mechanical property, the balance realizing anionic reactive properties of nylons is improved simultaneously.
The present invention also aims to the preparation method providing above-mentioned anionic reactive nylon, it is simple and easy to do.
According to the present invention, provide a kind of solid lubrication anionic reactive nylon, it is prepared through polyreaction by the composition comprising reaction nylon synthon and solid lubricant; Wherein, in the composition, the content of described reaction nylon synthon is 92-98 % by weight, and the content of described solid lubricant is 2-8 % by weight.
